Humans are visual. It's no surprise their social media are filled with pictures and images that show these visuals off. No matter how great the text is, no one will see it unless it’s accompanied by amazing visuals to grab people’s attention. When I design for social, I like to look at the whole social strategy and design to amplify the message. I never want one image to stick out, all images should be an amazing collection that works together to create a cohesive picture in the viewers' mind.
